My invention relates to improvements in means for and methods of making printing chases for printed matter to be set at an angle.

By way of explanation, frequently in the printing industry, advertising copy must be set up in type from layout drawings with side margins at an angle to the line of printing. Compositors experience considerable difficulty in setting up such copy because it is difficult to ascertain the correct angle to the line of printing of 'the side margin required.

Having the foregoing in mind, it is the primary object of my invention to provide for accurately setting up such copy quickly and easily in a chase without guess work resulting in mistakes costly in the printing trade.

Other objects, subordinate in nature, together with the precise nature of my improvements will be readily understood when the succeeding description and claim are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in plan of a miter gauge for use in the practice of my invention;

Figure 2 is a view in front end elevation of the same;

Figure 3 is a Figure 4 is a view in end parts disassembled;

Figure 5 is a view in perspective of the gauge;

Figure 6 is a view of the copy of the printed matter shown diagrammatically Figure 7 is a view in plan illustrating the manner in which the gauge is used to determine the angle of the marginal edge of the copy;

Figure 8 is a similar view illustrating the manner in which the gauge is used on a saw table in making the side pieces for the chase;

Figure 9 is another similar view illustrating the manner in which the end pieces of the chase are made; and

Figure 10 is a view in front elevation of the chase assembled.

Referring now to the drawings byv numerals according to the practice of my invention illustrated, a miter gauge I is provided for use in a manner presently set forth, and the structure of which will now be described in detail.

The miter gauge I comprises a substantially rectangular, elongated body panel 2 with a leading front end edge 3 and a levelling side edge 4. The panel 2 is provided with a thickened rear end portion which may be formed by a substantially square bottom block 5 secured by corner view in edge elevation of the same; elevation with the 2 screws 6 therein to what constitutes the bottom face of said panel 2. Forwardly of the block 5, a flat gauging segment I with a straight gauging edge 8 is pivoted on the front end corner 9 of said panel 2 remote from the levelling side edge 4 for rotation on said panel 2 in engagement with the bottom face of the panel 2, said segment I clearing the block 5 with its gauging edge 8 adapted to extend forwardly of the leading end 3 of said panel 2 in different settings of said segment. The pivot for said segment I comprises a suitable bolt III with a wing nut II and washer l2 thereon on the top face of said panel 2 for clamping said segment I to the bottom of said body panel 2 in different set positions. The segment I is of the same thickness as the block 5 so that when said gauge I is laid on a table bottom face downward, it will lie flat on the table. The corner 9 is rounded to clear the gauging edge 8.

The miter gauge I described in the foregoing is especially designed for use, as described in the following, in making a chase C such as is shown in Figure 10 for printed matter, or the like, not shown, set up from a copy sheet I3, such as is shown in Figures 6 and 7 and with margin side edges I I oblique to the end edges I5 and to the line of printing.

In using the miter gauge I for the abovepurpose, the angle of the margin side edges I4 of the copy sheet I3 is first determined by placing said sheet flat on a table I6, or the like, with the bottom end of said sheet against a straight edge N, then placing the body panel 2 of the gauge i bottom side down on the table I6 with the levelling edge 4 against said straight edge I1 and then setting the gauging segment I to fit the gauging edge 8 thereof against one margin side edge I4. This gives the angle for the inner sides of the chase C.

With the miter gauge set as described, a fiat block I8, of wood, of a suitable size, is next disposed, together with the set miter gauge I on the usual movable table I9 of a circular saw machine I9, such as is usually provided in printing establishments, with the levelling edge 4 of said gauge I positioned against the usual work-feeding gauge bar 20 on said table, the block I8 positioned against said bar 20 with one side fitted flush against the gauging edge 8, said block being tilted for this purpose sidewise relative to the plane of the saw, and the rear end of the body panel 2 being positioned against the usual width gauge 2I of such saw machines set for cutting of a narrow piece from the block I8. The table I9 is then moved to feed the block I8 to the saw 22 and cut from one side of said block IS a side piece 23 for the chase C having an inner side edge 24 inclining at an angle corresponding to that of one margin side edge ll of the copy sheet l3 relative to the printing line.

The saw table I9 is next retracted and with the miter gauge I positioned thereon as described, the block I8 is reversed on said table, side for side, the other side fitted against the gauging edge 8 and the above described operation repeated to cut from the other side of the block it the other side piece 25 for the chase C with an inner side edge 28 inclining in correspondence with the other margin side edge ill of the copy sheet 83.

In cutting the side pieces 23, 25, a center piece 21, shown in Figure 9, is left out from the block 83 with side edges 28 inclined at an angle to its ends corresponding to the angle of the inner side edges 23, 25 of the side pieces 23, '25.

End pieces for the chase C are then cut from this center piece 2?, as follows. Referring now to Figure 9, the side pieces 23, 25 are imposed on the saw table l9 with the inclined inner side edges 26, 35 engaged flush and with the straight edge of one side piece 23 positioned against the bar 23. The side pieces 23, 25 are next adjusted endwise relatively so that the inclined edge 26 of the side piece 23 engaging the bar 23 forms a lateral ledge 28 inclined laterally of the saw 22 at the same angle as the inner side edges 23, 26 of the side pieces 23, 25, and the other side piece 25 forms a shoulder 29 parallel with the saw 22. The width of the ledge 28 is regulated by the width guage 2 l a support 38 imposed against said width gauge and against one end of the side piece 25, and a spacing block 36 of the same width as that desired in the ledge 23, that is from the shoulder 29 to the small end of the piece 23, is interposed between the said gauge 2! and the adjacent end of the side piece 23. The width gauge M is then adjusted to slide the support 39, spacing block 3! and the side pieces 23, 25 toward the cutting plane of the saw 22 until the small eiid of the side piece 23 is in said plane of the near side of the saw 22. The center piece 21 is then positioned endwise against the shoulder 29 with one side thereof fitted on said ledge 28 and held by hand in this position, coplanar with the pieces 24, 25 while the table 56 is fed forwardly to cut an end piece 32 for the chase C off said center piece 27 of the width of said ledge 28. The

table It is then retracted, and the center piece 21 again positioned on the ledge 28 and against the shoulder 29 and another end piece 33 is cut off the center piece 21, for the chase C, in the same manner as described with reference to the end piece 32.

The manner in which the side pieces 28, 25 and the end pieces 32, 33 for the chase C are assembled to form the chase is shown in Figure 10.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

The herein described method of forming a printing chase having side and end pieces comprising feeding a rectangular fiat block horizontally to a vertical saw with the side edges of the block being inclined to said saw to cut from opposite sides thereof along diagonal lines, side pieces for the chase having a side oblique to the ends thereof and a center piece having side edges oblique to the ends of the same, imposing one side piece on top of the other with oblique sides engaged fiush and the lower side piece extending at one end from the other side piece to form an abutment face out of one end of the top side piece and an inclined ledge on the oblique side of the other side piece of a width from said abutment face corresponding to the width of the end pieces to be formed, arranging one end of the center piece on said ledge with said end abutting said face and one side abutting said ledge, and feeding said side pieces and center piece to said saw to cut crosswise of said center piece in a plane parallel to said face and spaced therefrom in correspondence with the width of said ledge to cut an end piece equal in thickness to the width of the ledge and with oblique ends parallel with the oblique sides of the side pieces.
